The base pairs found in DNA are key to its ability to store protein-coding information, but they also give the molecule useful structural properties. Getting two complementary strands of DNA to zip up into a double helix ...

The genetic information of every cell is encoded in the sequence of the DNA double helix. Double strand breaks in the DNA, which can be induced by radiation, are a dangerous threat to the cells, and if not properly repaired ...

DNA, our genetic material, normally has the structure of a twisted rope ladder. Experts call this structure a double helix. Among other things, it is stabilized by stacking forces between base pairs. Scientists at the Technical ...

The structure and dynamics of the DNA double helix are influenced in a decisive way by the surrounding water shell. New experiments in the ultrafast time domain show that the first two water layers at the DNA surface generate ...

A new study could explain why DNA and not RNA, its older chemical cousin, is the main repository of genetic information. The DNA double helix is a more forgiving molecule that can contort itself into different shapes to absorb ...

Bioengineers at the University of California, San Diego have developed an electrical graphene chip capable of detecting mutations in DNA. Researchers say the technology could one day be used in various medical applications ...

We've been able to see them for over a hundred years, but only now are scientists beginning to get to the bottom of what's happening inside membraneless organelles – compartments within cells that really do have no boundaries.

Rutgers University scientists have discovered the three-dimensional structure of a gene-specific transcription activation complex, providing the first structural and mechanistic description of the process cells use to turn ...
